BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a sideblock fusion bonding system made of a synthetic resin, and more particularly, to a synthetic resin sideblow fusion bonding system for producing a buoy by fusion-bonding extruded synthetic resin bumps by heat.

Generally, buoys used in aquaculture are mainly composed of styrofoam. Conventional styrofoam buoys are used by winding a binding wire between two cylindrical bodies.

In the so-called foam foam buoy constructed as described above, since an excessive external force is applied to the groove portion where the binding wire is wound, it is easily damaged or changed by wave or the like during prolonged use.

If the outer surface of the styrofoam buoy is broken as described above, the marine is contaminated by broken fragments, and the damaged styrofoam buoy is difficult to use, so that the problem of environmental pollution becomes large because it is treated in a state where it is covered with the shore or the yard.

In order to solve such a problem, a synthetic resin buoy is used which is formed by molding a body having a space in an inner diameter thereof with synthetic resin.

Figs. 1A and 1B show conventional synthetic resin buoys, respectively. As shown in the figure, the synthetic resin buoy 10 is manufactured by molding polypropylene (PP), random polypropylene (RPP) or high density polyethylene (HDPE) into a cylindrical shape by chemical crosslinking.

The synthetic resin buoy 10 manufactured in this way is mainly manufactured by injection molding synthetic resin into a mold and extrusion molding. As shown in FIG. 1B, the extrusion molding method can not be manufactured as a single product, It is common.

Therefore, there is a need for a separate device or system for joining the synthetic resin buoys separated and manufactured into two pieces.

FIGS. 2 to 8 show a synthetic resin heat sink system according to an embodiment of the present invention. As shown in the figure, the synthetic resin hot-melt adhesive system of the present invention comprises a lower table; A first holding unit that is seated and fixed on an upper surface of the lower table; A second holding unit movably connected between the first holding unit and the second holding unit so as to be movable in one direction on the upper surface of the lower table, And a heat fusion unit configured to apply heat.

The lower base 100 may be a substantially plate-shaped conventional support, and the lower part may include a moving roller 110. The lower table 100 may include a controller 120 and other utilities for driving the system of the present invention.

A first guide rail 130 and a second guide rail 140 are provided on the upper surface of the lower table 100. The first guide rail 130 is for sliding movement of the second holding unit 300 and the second guide rail 140 is for sliding movement of the heat welding unit 400.

A first holding unit 200 for fixing one side of the two divided buoys 10 is provided on the upper surface of the lower table 100. The first holding unit 200 includes a first molding case 210 having a shape corresponding to one side of the buoy 10; A first support 220 connected to a rear surface of the first molding case 210; And a first holder 230 provided in the first molding case 210 for fixing or releasing one side of the buoy 10.

One side of the buoy 10 mounted on one side of the first molding case 210 is connected to the side of the first molding case 210, 1 holder 230, as shown in Fig.

The first holder 230 can selectively fix or unlock the one side of the buoy 10 as shown in Fig. The first holder 230 includes a first air nozzle 231 for fixing the buoy 10 through air suction; And a first moving pipe 232 connected to the first air nozzle 231 through the center and protruded or inserted outside.

Therefore, the first holder 230 can suck air on one side of the buoy 10 by inserting air through the first air nozzle 231 in a state where one side of the buoy 10 is placed inside the first molding case 210 And one end of the buoy 10 can be detached by terminating the air suction of the first air nozzle 231 and protruding the first moving pipe 232 to the outside when the heat fusion is completed.

A second holding unit 300 is provided on the upper surface of the lower table 100 in a direction opposite to the first holding unit 200 in order to fix the other side of the two divided buoys 10. The second holding unit 300 also includes a second molding case 310, like the first holding unit 200; A second support 320; And a second holder 330.

However, the second holding unit 300 is configured to be movable in the direction of the first holding unit 200 along the lower table 100. More specifically, the second holding unit 300 slides along the first guide rail 130 provided on the upper surface of the lower table 100, and each component for sliding movement can be configured by a known technique have.

The second holding unit 300 can move along the first guide rail 130 in the direction of the first holding unit 200 while the other side of the buoy 10 is fixed inside the second molding case 310 .

On the upper surface of the lower base 100, a heat-sealing unit 400 which is seated movably between the first holding unit 200 and the second holding unit 300 is connected. The heat fusing unit 400 heats the buoys 10 fixed inside the holding units 200 and 300 to be thermally fused to each other.

The heat fusion unit 400 includes an outer frame 410 in the form of a window frame as shown in Fig. 6; And a plurality of heating units 420 formed in the outer frame 400 so as to be spaced apart by a predetermined distance.

The outer frame 410 moves along the second guide rail 140 provided on the upper surface of the lower table 100 and moves in a direction perpendicular to the first guide rail 130 from the upper surface of the lower table 100 .

Accordingly, the outer frame 410 moves between the first holding unit 200 and the second holding unit 300 to heat the buoys 10 fixed to the holding units 200 and 300.

In the open window of the outer frame 410, a plurality of heating units 420 are spaced apart by a predetermined distance. The heating unit 420 may be provided as a general heating line. However, in a general heating line, the temperature of the upper heating line is relatively increased due to the convection phenomenon in the buoy 10 during the heating process so that the buoy 10 can not be heated evenly Lt; / RTI > Therefore, it is preferable that the heating unit 420 of the present invention is constituted by an infrared lamp heater which is a method of heating by radiant heat.

The heating unit 420 may include a vertical heating unit 421 and a horizontal heating unit 422 arranged in a horizontal direction. The horizontal heating part 422 may be formed as one upper part and one lower part and may be connected to the outer frame 410 so as to be movable up and down along the outer frame 410.

More specifically, a plurality of vertical heating parts 421 are disposed at upper and lower ends of the outer frame 410 at predetermined intervals, respectively, and a horizontal heating part 422 is disposed on the outer front and rear surfaces of the vertical heating part 421 So that no interference occurs in the movement.

The heating position can be adjusted according to the size of the buoys 10 while the horizontal heating portion 422 moves up and down. The plurality of vertical heating portions 421 may be separately controlled so that only a part of the buoys 10 may be heated or a different heating temperature may be set.

Hereinafter, the operating state of the synthetic resin heat sink system according to the present invention will be described in detail.

First, a buoy step (S100) is performed in which the buoys 10 are respectively mounted on the first holding unit 200 and the second holding unit 300. The buoys 10 divided into two parts are inserted into the molding space 211 of the first molding case 210 of the first holding unit 200 and the molding space 211 of the second molding case 310 of the second holding unit 300, In the space 311.

After the first holding unit 200 and the second holding unit 300 are coupled in the state where the buoy 10 is mounted, the first and second holders 230 and 330 fix the buoy The sub-table fixing step (S200) is performed.

That is, after the buoys 10 are respectively mounted on the respective holding units 200, the second holding unit 300 is moved in the direction of the first holding unit 200, 230 and the second holder 330 fix the buoys 10 by air suction, the buoys 10 can be fixed in the molding spaces 211, 311 in a state of being correctly seated.

A thermal welding unit preparation step S300 in which the thermal welding unit 400 enters between the holding units in a state where the second holding unit 300 is spaced from the first holding unit 200 by a predetermined distance, .

The second holding unit 300 may be positioned by sliding the heat-sealing unit 400 between the holding units while the second holding unit 300 is retracted from the first holding unit 200 by about 70 mm in the heat-sealing unit preparing step S300.

A heating step S400 for applying heat to each buoy 10 is performed in a state where the heat fusion unit 400 is positioned. In the heating step S400, the vertical heating part 421 movable in the vertical direction can move to the right position so as to correspond to the size of the buoy.

In the heating step S400, only the vertical heating part 421 at the outermost one of the horizontal heating part 422 and the vertical heating part 421 is heated first, and the remaining vertical heating part 421 is heated .

This is because the outer surface of the buoy is graded and the inside is not graded, so the two parts have different melting points. Thus, after the outer surface of the buoy is first heated, the buoy can be uniformly heated on the entire surface by heating the buoy inside after about one second has elapsed.

After the heating is completed for a predetermined period of time, an adhesion step S500 is performed in which the thermal fusing unit 400 is retracted to the original position and the holding units are pressed against each other to adhere the buoys 10. In the bonding step S500, the second holding unit 300 is pressed in the direction of the first holding unit 200 for about 40 seconds, so that the holding units can be tightly adhered to each other.

When the buoys 10 are fused to each other, a removing step (S600) for detaching the buoys 10 from the holding unit is performed. In the removal step (S600), the moving pipes (232, 332) of the holding unit are protruded forward so that the buoys (10) inside the holding unit can be easily removed.
